Answer:
Sodium ions flow passively from high concentration to low concentration.
Explanation:
When a ligand binds to a ligand gated, there's always a flow of ions, in this case we talk about sodium. When the bind is produced, the channel undergoes a conformational change that determines its opening. Remember that the channel, is a protein. In this example we don't talk about a bomb, that's why we suppose that sodium ions are not pumped. As the flow is in favor of gradient, ions always go from high concentration to low.
We say that ions flow PASSIVELY because Ionic channels are sort of passive transport, we don't need ATP.
YY and Yy because Y is dominant over y so you would end up with one homozygous dominant pea plant and one heterozygous dominant pea plant
The right option is inducible
defense
Inducible defense is a defense mechanism
activated by plants against herbivore attacks.This mechanism is activated through
a prior encounter with a consumer that confer some level of resistance to
subsequent attacks. For the question given above, production of chemical defenses by an algae after it has been grazed upon by a
herbivore is an example of inducible
defense.
Answer:
Stems and root
Explanation:
Auxins facilitate stem elongation while inhibiting axillary bud formation, ensuring apical dominance. The root, branches, and stem and tip all contain them. Hydroxy Acetic Acid is a perfect example. Auxin is indeed a growth hormone that facilitates cell elongation and is formed in the stem tip.
